Cooling Electronics with Graphene-based Film

How many fans does it take to keep your computer from overheating? Electronic systems accumulate a great deal of heat, mostly due to the ever-increasing demand on functionality. Computer users have been using cool air (and even liquid) to reduce heat, but now researchers at Chalmers University of Technology have developed a method for efficiently cooling electronics using graphene-based film. The film is a mere 20 micrometers thick, yet has four times the thermal conductivity capacity of copper. Cooling Electronics, Protecting the Environment Getting rid of excess heat in efficient…

Brain-like Computers from Optical Fibers

Computers that function like a human brain could soon become a reality thanks to new research using optical fibers made of speciality glass. This research has the potential to allow a faster and smarter brain-like computer that can learn and adapt. Researchers from the Optoelectronics Research Centre (ORC) at the University of Southampton, UK, and Centre for Disruptive Photonic Technologies (CDPT) at the Nanyang Technological University (NTU), Singapore, have demonstrated how neural networks and synapses in the brain can be reproduced with optical pulses as information carriers, using special fibers…
